To smoosh or not to smoosh....

We finally decided on a double middle for our daughter after hours of discussions and mind changes. Her name is Sena ( Sen-nah) EllaRose. Both middles have significance for our family. The question. Do we hyphenate? Smoosh? Or leave as EllaRose. We *might* call her by her middle name. It's undecided. But, we'd want people to say EllaRose-- not just Ella. What's the best way to have that happen?
